awk help to get stale path information

lawrenzo_1 — Wed, 19 Mar 2008 13:18:23 GMT

Hello all,

Please can someone help me with awk syntax ...

I have a report that details servers / fibre cards and whether there are any stale paths. I want the awk sytax to only report on the server, disk and stale paths when the string "stale is present" here is a snippit from my report:

Start task on cgcu180a
# START OUTPUT SANCheck
cgcu180a.eu.unilever.com

so I am looking for the below output only to report on the disk with stale paths

cgcu180a
4 PATHS to dsk11072 (HWID:423)
2 to SCSI: 5 stale
2 to SCSI: 6 valid

I am working this out slowly but not getting very far ....

the problem I have is for awk to identify stale then report the disk section ....

any help is greatly appreciated as always :-)

Thanks

Chris

Hi Chris:

# awk '/PATHS/ {LAST=$0};/stale/ {print LAST;print $0;getline;print $0}' file

...or, of course, simple pipe the command's output to the awk script above.

Regards!

here is my effort so far:

ah missed you suggestion James ....

Thanks,

let me see if I can incorporate that with each server listed.

Chris.

Hi (again) Chris:

...and I missed the the host identifier in the output, do:

# awk '/START/ {getline;print};/PATHS/ {LAST=$0};/stale/ {print LAST;print $0;getline;print $0}' file

Regards!

Thanks James,

it works a treat ...

I am still working on awk programming but not finding much time however I have come up with some syntax for easier tasks thanks to the information you provide ( and other ITRC users )

so much appreciated!

Chris.

>I am still working on awk programming

You could do it like C, if that's a help.

>JRF: print LAST;print $0;getline;print $0

I'm not sure why you are printing one entry after the stale entry. This wouldn't handle stale being last. If there were multiple stale entries, you would repeat the disk.

The following only prints the stale entries:
awk '
BEGIN { last = "" }
/START OUTPUT SANCheck/ {
getline
print $0
}
/PATHS/ {
last = $0
}
/stale/ {
if (last != "") {
print last
last = ""
}
print $0
}' file
